Abstract The results of a search for narrow resonances ine + e − annihilation at centre-of-mass energies between 7.23 and 10.34 GeV are presented. The experiment was performed using the MD-1 detector at the VEPP-4 storage ring. The total luminosity integral of 16 pb−1 was taken. There is no evidence that new states exist. The upper limits on the leptonic widthΓ ee of possible resonances are less, by a factor of 10–80, than theΓ ee for the ϒ(1S) meson.
